你好~~
(xy)乘(2xy二次)=?
-----------------------------------------------------------------------------------------------------------------
(xy) x 2xy²
=2x¹+¹y²+¹
=2x²y³
答案: 2x²y³
(xy)乘(2xy二次)=?
-----------------------------------------------------------------------------------------------------------------
(xy) x 2xy²
=2x¹+¹y²+¹
=2x²y³
答案: 2x²y³

xy * 2xy^ 2
= 2x ^2 y^3
a^n * a^m
= a ^(n+m)
= 2x ^2 y^3
a^n * a^m
= a ^(n+m)

(xy) x 2xy²
=(xy)乘(2xy二次)
=2乘x二次乘y三次
2xy(2)
=4xy
=(xy)乘(2xy二次)
=2乘x二次乘y三次
2xy(2)
=4xy
